General information regarding the CE marking

HAMEG instruments fulfi ll the regulations of the EMC directive. The conformity test made by HAMEG is based on the actual generic- and product standards. In cases where different limit values are applicable, HAMEG applies the severer standard. For emission the limits for residential, commercial and light industry are applied. Regarding the immunity (susceptibility) the limits for industrial environment have been used.

The measuring- and data lines of the instrument have much infl uence on emmission and immunity and therefore on meeting the acceptance limits. For different applications the lines and/or cables used may be different. For measurement operation the following hints and conditions regarding emission and immunity should be observed:

1. Data cablesFor the connection between instruments resp. their interfaces and external devices, (computer, printer etc.) suffi ciently screened cables must be used. Without a special instruction in the manual for a reduced cable length, the maximum cable length of a dataline must be less than 3 meters and not be used outside buildings. If an interface has several connectors only one connector must have a connection to a cable.Basically interconnections must have a double screening. For IEEE-bus purposes the double screened cables HZ72S and HZ72L from HAMEG are suitable.

2. Signal cablesBasically test leads for signal interconnection between test point and instrument should be as short as possible. Without instruction in the manual for a shorter length, signal lines must be less than 3 meters and not be used outside buildings.Signal lines must screened (coaxial cable - RG58/U). A proper ground connection is required. In combination with signal generators double screened cables (RG223/U, RG214/U) must be used.

3. Infl uence on measuring instruments.Under the presence of strong high frequency electric or magnetic fi elds, even with careful setup of the measuring equipment an infl uence of such signals is unavoidable.This will not cause damage or put the instrument out of operation. Small deviations of the measuring value (reading) exceeding the instruments specifi cations may result from such conditions in individual cases.

Alignment procedure HM8018

Measuring equipment required: – Oscilloscope 20 MHz (e.g. HM303) – Frequency counter (e.g. HM8021) – Digital Multimeter DMM (e.g. HM8012) – Load 100 kΩ 0.1%, – Load 1 kΩ 0.1% – Capacitor 470 pF (PP or Polysulfon) – Capacitor with known value between 10...16 nF 0.1%

Presettings: To start the calibration, fi rst adjust the R-trimmer „Pro-

be comp.“ and „Display Zero“ at the front panel to center position. Disconnect all cables of the frontpanel HM8018.

1. Test of oscillator frequency: Connect frequency counter (TI measuring) to testpoint

„Synchro“. Set LC-Meter to range 2 pF, „G“. Adjust period to 6280 ps ±25 ps with R111.

2. Adjustment of measuring frequency: Set LC-Meter to the ranges described below. Adjust period

time as following: 2 μF VR103 (3) 6283 μs ±1 μs 200 nF VR102 (2) 628.3 μs ±1 μs 200 pF VR101 (1) 62.83 μs ±1 μs

3. Adjust offset (PD): Connect oscilloscope (AC-coupling, max. sensitivity) to TP5

and set LC-Meter to range 200 nF, „G“. Adjust amplitude to minimum with VR106 (6).

4. Adjust offset (Uref): Connect DMM (VDC)to TP5. Set LC-Meter to 200 mH. Adjust

VR109 (9) to 0 ±1 mV.

5. Symmetry: Set LC-Meter to 200nF, „G“. Connect resistance 100 kΩ

to the banana jacks and the oscilloscope (AC, 10 mV/Div., 0,1 ms/Div.) to TP7. Adjust VR108 (8) for same amplitude.

6. Adjust offset (Vin): Disconnect all cables from the instrument. Set LC-Meter

to range 200 nF. „G“. Connect DMM (VDC) to TP7. Adjust VR110(10) to 0 ± 1 mV.

7. Range selection und gain: Connect resistance 1 kΩ to the banana jacks. Set LC-Meter

to 200 mH. Repeat the following steps several times.

a) Set range to „Rs“. Adjust the display of LC-Meter to 1000 ±1 Digit by means of VR105 (5).

b) Set range to „G“. Adjust the display of LC-Meter to 1000 ±1 Digit by means of VR401 (21).

8. Adjustment of input capacitance: Connect capacitor 470 pF to banana jacks. Set LC-Meter to

200 pF, „G“. To adjust the input capacitance, it is necessary to close the module housing (a. and b.).

a) Connect oscilloscope (AC-coupling) to TP5, with modul cover closed. Pass the cable through holes in the module cover. Reduce amplitude to minimum by means of VR107 (7).

b) Connect oscilloscope to TP4 [same way as a)]. Remove ca-pacitor 470 pF. Reduce amplitude to minimum by means of VR111 (11).

9. Range selection „C“, „L“: Remove all cables from HM8018. Set LC-Meter to 200 pF,

„C“. Adjust „Display Zero“ (front panel) to 0 ±3 digit on the display of HM8018.

a) Connect Kelvin probe HZ18 to Kelvin input (5-pin diode jack) and reduce the reading to 0 ±3 digit via „Probe comp.“ on front panel.

b) Disconnect HZ18 and connect a known capacitor between 10 nF and 16 nF to the banana jacks. Set LC-Meter range to 20 nF, „C“. Adjust VR104 (4) for same reading as value of the capacitor.
